What did i do wrong in this rank script? [Not Answered]

I made a rank script and used rgb for the coloring but none of the ranks are colored. I think i did everything right and have made previous scripts before but i don't know why it isn't working.

game.Players.PlayerAdded:connect(function(plr)
    plr.CharacterAdded:connect(function(char)
        local rank = plr:GetRoleInGroup(1148703)
        local color = Color3.new(255/255, 255/255, 255/255)
        if rank == "Guest" then
            color = Color3.new(255/255, 255/255, 255/255)
        elseif rank == "Member" then
            color = Color3.new(255/255, 255/255, 255/255)
        elseif rank == "Abuse Reporter" then
            color = Color3.new(117/255, 69/255, 71/255)
        elseif rank == "Trial-Moderator" then
            color = Color3.new(0/255, 0/255, 0/255)
        elseif rank == "Moderator" then
            color = Color3.new(52/255, 117/255, 0/255)
        elseif rank == "Head-Moderator" then
            color = Color3.new(255/255, 149/255, 0/255)
        elseif rank == "Supervisor" then
            color = Color3.new(17/255, 0/255, 255/255)
        elseif rank == "Manager" then
            color = Color3.new(117/255, 107/255, 255/255)
        elseif rank == "Administrator" then
            color = Color3.new(54/255, 14/255, 255/255)
        elseif rank == "Head-Administrator" then
            color = Color3.new(19/255, 255/255, 7/255)
        elseif rank == "Chief Staff Officer" then
            color = Color3.new(139/255, 1/255, 132/255)
        elseif rank == "Chief Operational Officer" then
            color = Color3.new(254/255, 255/255, 180/255)
        elseif rank == "Chief Executive Officer" then
            color = Color3.new(1/255, 74/255, 74/255)
        elseif rank == "Developer" then
            color = Color3.new(138/255, 138/255, 138/255)
        elseif rank == "Co-Owner" then
            color = Color3.new(8/255, 255/255, 239/255)
        elseif rank == "Group Owner" then
            color = Color3.new(255/255, 8/255, 235/255)
        elseif rank == "Mod King -Owner-" then
            color = Color3.new(255/255, 0/255, 0/255)
        end
        print(plr.Name.." just joined with rank '"..rank.."'")
        if rank ~= "Guest" then
            local rankd = game.ServerStorage.Rank:Clone()
            rankd.Parent = char.Head
            rankd.TextLabel.Text = rank
            rankd.TextLabel.TextColor3 = color
        end
    end)
end)
